Mistakes are made when you're trying hard.
Sounds like somebody made a mistake... Oh well.
I hate sitting for hours while the ground units rescue, extricate and/or transport the patient to the LZ, but the ideais to get the patient to definitive care as quickly as possible. Sometimes there isn't a viable patient after all that; sometimes air transport isn't needed, and we leave empty; but I have seen the medical crew doing everything they can to keep the patient alive, and sometimes that's just not possible. I would rather be called in anticipation than waste the few minutes that might determine the outcome.
